The Mersen FR10GR69V4 is a genuine Protistor® ultra-fast semiconductor fuse engineered to provide full-range protection for sensitive power electronic equipment. Rated at 4 A and 690 V AC, this gR-class fuse is specifically designed to protect semiconductor devices from both overload and short-circuit faults, making it ideal for demanding industrial applications.
Manufactured in the internationally recognised 10 × 38 mm cylindrical format, the FR10GR69V4 is suitable for use in compatible fuse holders and is widely specified for inverter systems, UPS installations, variable speed drives and other semiconductor-based power conversion equipment. Its low let-through energy (I²t) helps minimise thermal stress on expensive electronic components during fault conditions.
As part of the Mersen Protistor® range, the FR10GR69V4 offers exceptional current limitation, rapid fault clearance and excellent cycling capability, helping improve equipment reliability while reducing maintenance costs and downtime.
The FR10GR69V4 has been developed specifically for protecting modern semiconductor devices where extremely rapid fault clearance is essential. Its gR operating characteristic provides full-range protection against overloads and short circuits while limiting the energy delivered to IGBTs, diodes, thyristors and other power semiconductors.
The compact 10 × 38 mm format allows straightforward installation into compatible fuse holders, making the fuse suitable for OEM equipment, industrial automation systems and maintenance applications requiring dependable semiconductor protection.
